A microphysiological system of sterile injury demonstrates neutrophil reverse migration via macrophage-derived extracellular vesicle crosstalk.

Persistent neutrophilic inflammation can lead to tissue damage and chronic inflammation, contributing to non-healing wounds. The resolution phase of neutrophilic inflammation is critical to preventing tissue damage, as observed in diseases characterized by influx of neutrophils such as atherosclerosis and non-healing wounds. Animal models have provided insight into resolution of neutrophilic inflammation via efferocytosis and reverse migration (rM); however, species-specific differences and complexity of innate immune responses make translation to humans challenging.

Molecular dynamics at immune synapse lipid rafts influence the cytolytic behavior of CAR T cells.

Chimeric antigen receptor T cells (CART) targeting CD19 through CD28.ζ signaling induce rapid lysis of leukemic blasts, contrasting with persistent tumor control exhibited by 4-1BB.ζ-CART.

Use of Practices to Reduce of Sudden Unexpected Infant Death among Caregivers of Opioid Exposed Newborns.

Objectives: Sudden unexpected infant death (SUID) occurs disproportionately among opioid exposed newborns (OENs) compared to those unexposed. The extent that primary caregivers of OENs adhere to SUID-reducing infant care practices is unknown. We examined rates of SUID-reducing practices (smoking cessation, breastfeeding, and safe sleep [supine sleep, room-sharing not bed-sharing, nonuse of soft bedding or objects]) in a pilot sample of caregivers of OENs.

Ultra-fast single-crystal CVD diamonds in the particle time-of-flight (PTOF) detector for low yield burn-history measurements on the NIF (invited).

The Particle Time of Flight (PTOF) diagnostic is a chemical vapor deposition diamond-based detector and is the only diagnostic for measuring nuclear bang times of low yield (<1013) shots on the National Ignition Facility. Recently, a comprehensive study of detector impulse responses revealed certain detectors with very fast and consistent impulse responses with a rise time of <50 ps, enabling low yield burn history measurements. At the current standoff of 50 cm, this measurement is possible with fast 14 MeV neutrons from deuterium-tritium (DT) fusion plasmas.

Diagnostic development and needs for laser driven MeV x-ray radiography.

Laser-driven MeV x-ray radiography of dynamic, dense objects demands a small, high flux source of energetic x-rays to generate an image with sufficient quality. Understanding the multi-MeV x-ray spectrum underscores the ability to extrapolate from the current laser sources to new future lasers that might deploy this radiography modality. Here, we present a small study of the existing x-ray diagnostics and techniques.
